Selenophenolato hydrido iron(II) complexes 1-3 cis-[(H)(SeAr)Fe(PMe3)(4)] (Ar = C6H5 (1), p-MeOC6H4 (2) and o-MeC6H4 (3)) could catalyze transfer hydrogenation of aldehydes and ketones. Among the three complexes, catalyst 1 exhibited the highest catalytic activity. The catalytic reactions took place under very mild conditions, using isopropanol as solvent and hydrogen source, (BuONa)-Bu-t as base under 60-80 degrees C. This catalytic system has good tolerance for many functional groups, such as halides, C=C double bonds, nitro groups and cyano groups at the phenyl ring of the substrates.

Xia, YP; Ouyang, L; Liao, JH; Yang, X; Luo, RS in [Xia, Yanping; Ouyang, Lu; Liao, Jianhua; Yang, Xiao; Luo, Renshi] Gannan Med Univ, Sch Pharm, Ganzhou 341000, Jiangxi, Peoples R China published Chemoselective Transfer Hydrogenation of alpha,beta-Unsaturated Ketones Catalyzed by Iridium Complexes in 2021.0, Cited 72.0. The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7.

Efficient chemoselective transfer hydrogenation of the C=C bond of alpha,beta-unsaturated ketones has been developed, using the iridium complexes containing pyridine-imidazolidinyl ligands as catalysts and formic acid as a hydrogen source. In comparison with organic solvents or H2O as solvent, the mixed solvents of H2O and MeOH are critical for a high catalytic chemoselective transformation. This chemoselective transfer hydrogenation can be carried out in air, which is operationally simple, allowing a wide variety of alpha,beta-unsaturated substrates with different functional groups (electron-donating and electron-withdrawing substituents) leading to chemoselective transfer hydrogenation in excellent yields. The practical application of this protocol is demonstrated by a gram-scale transformation.

Reduced graphene oxide (rGO)-NaBH4 is reported as mild and efficient catalyst-system for chemo-/ regioselective reduction of structurally different aliphatic, aromatic as well as alpha,beta-unsaturated aldehydes and ketones in water. The rGO was prepared by reducing graphene oxide using Tulsi leaf extract as bio-reductant. Operational simplicity, ambient reaction condition, high yield of pure products (80-97%), no by-product formation, no use of column chromatography for purification are the salient features of the envisaged protocol. Furthermore, the recovered TRGO was recycled and reused for subsequent reductions up to five times without any loss in activity. (C) 2019 Published by Elsevier Ltd.

The catalytic alkylation of ketones with alcohols via the hydrogen borrowing methodology (HB) has the potential to be a highly efficient approach for forming new carbon-carbon bonds. However, this transformation can result in more than one product being formed. The work reported here utilises bidentate triazole-carbene ligated iridium and rhodium complexes as catalysts for the selective formation of alkylated ketone or alcohol products. Switching from an iridium centre to a rhodium centre in the complex resulted in significant changes in product selectivity. Other factors – base, base loading, solvent and reaction temperature – were also investigated to tune the selectivity further. The optimised conditions were used to demonstrate the scope of the reaction across 17 ketones and 14 alcohols containing a variety of functional groups. A series of mechanistic investigations were performed to probe the reasons behind the product selectivity, including kinetic and deuterium studies.

Chalcones, as a large group of organic compounds, are widely implemented in various types of anticancer therapeutics. These plant metabolites are present in fruits, vegetables, spices, and have anti-tumor, anti-inflammation, immunomodulation, antibacterial and anti-oxidative activities, as well as many other pharmacological and biological effects. The aim of the present study was to investigate cytotoxic effects, type of cell death and mechanism of action of the newly synthesized vanillin based chalcone analogs, (CH1) and (CH2) on human colon cancer HCT-116 and noncancerous (control) MRC-5 cell lines. In order to compare the effects of vanillin based chalcone analogs on investigated cell lines, as reference substances cisplatin (cisPt) and dehydrozingerone (DHZ) were used. Investigation of antitumor effect of chalcone analogs on HCT-116 cells was carried out by three methods MTT assay, flow cytometry and immunofluorescence analysis. The result of our investigation indicated that newly synthesized vanillin based chalcone analogs expressed powerful antitumor effect on cancer cells (HCT-116 cell line), while their effect on healthy cells (MRC-5 cell line) was not statistically significant. Vanillin based chalcone analogs caused overexpression and activation of mitochondrial Bax protein and caspase-3 in HCT-116 cells, indicating that their mechanism of antitumor action was mediated through activation of the inner apoptotic pathway. These results indicate possible usefulness of CH1 and CH2 in antitumor therapy whether through its direct cytotoxic effect or as adjuvant therapy. Our results indicate possible usefulness of CH1 and CH2 vanillin based chalcone analogs in antitumor therapy.

C3-(Trans-2-arylethenyl)carbonylated chlorophyll derivatives possessing a bacteriochlorin or chlorin pi-system were synthesized by cross-aldol (Claisen-Schmidt) condensation of methyl pyrobacteriopheophorbide-a or 3-acetyl-3-devinyl-pyropheophorbide-a bearing the C3-acetyl group with p-(un)substituted benzaldehydes under basic conditions. The corresponding porphyrin-type chlorophyll derivatives were prepared by the oxidation (17,18-didehydrogenation) of the chlorin-type. Their Qy absorption and fluorescence emission maxima in dichloromethane correlated well with Hammett substituent constants of the p-substituents. Several electron-withdrawing p-substituents suppressed the emission due to photoinduced electron transfer quenching in a molecule. The substitution sensitivities for their maxima and fluorescence quantum yields decreased in the order of bacteriochlorin-, chlorin- and porphyrin-type derivatives.

Strawberry is one of the most popular fruits because of its sensorial and functional properties. However, strawberry crop is sensitive to salt stress conditions. Despite plants have plasticity, high salt concentrations induce molecular, biochemical, and physiological responses in plants. There is evidence that the abscisic acid (ABA) hormone acts as a signaling molecule under stress conditions; however, the molecular mechanisms involved in the synthesis and homeostasis of ABA and in the induction of phytochemical antioxidant compounds under stress conditions remain unclear. In this study, the effect of stress induced by NaCl (salt stress – SS), with or without the simultaneous application of ABA, on the ABA, phenylpropanoids and L-ascorbic acid (AsA) metabolisms were evaluated. The physiological aspects (Na, Cl and proline concentration, photosynthetic variables) were also studied. The results showed that salt stress increases the Na and Cl content in the leaves, affects photosynthetic variables and triggers the production of proline, pelargonidin-3-O-glucoside, total phenolic compounds and AsA content, alongside the upregulation of several genes from the phenylpropanoid and flavonoid pathways. These effects were accompanied by the induction of compounds and transcripts related to ABA biosynthesis, conjugation and catabolism. Otherwise, the exogenous application of ABA in salt stressed plants promotes a shift in gene expression and metabolism to mitigate the stress. Therefore, salt stress affects the metabolism of ABA, phenylpropanoids and AsA in strawberry increasing phytochemical composition which is strongly associated with an ABA-dependent mechanism.
